The Atrium Vestae was a three-story 50-room palace in the ancient Roman Forum built around an elegant elongated atrium or court with a double pool. To the very east is an open vaulted hall with a statue of Numa Pompilius, the mythological founder of the cult.

The complex lay at the foot of the Palatine Hill, where a sacred grove that was slowly encroached upon lingered into Imperial times, when all was swept away by the Fire of Rome in 64. The House of the Vestals was rebuilt several times in the course of the Empire. After the dissolution of the College of the Vestals and the introduction of compulsory Christianity by Theodosius I in the late fourth century AD, the House of the Vestals continued to serve as a residence building. It now housed officials of the imperial court, and subsequently the papal court. Archaeological finds from this period include a hoard of 397 gold coins from the fifth century, and another 830 Anglo-Saxon coins dating from the 9th and 10th centuries. The site was abandoned in the 11th/12th century.

Today, remains of the statues of the Vestals can be seen in the Atrium Vestae.
